A species allied to the J. biserialis, L. and L., of Tasmania, but less than half the size, with more minute denticulations to the leaves, which are widely ovate, not round or decurrent at the anterior margin, nor bispiuous at the apex.

We owe our acquaintance with this plant to the liberality of our learned friend M. Montague, who most generously has communicated to us his own examples of such Antarctic species as we desired for comparison or examination, unhesitatingly confiding his unique specimens to the care of the post-office, that we might profit to the fullest by his labours, and avoid unnecessary errors. It differs from our /. unciformis in the larger and narrower leaves, which are acute and serrato-dentate along the inner margin.

Hab. Hermite Island, Cape Horn ; abundant, in the woods.

Species insignis. Caespites laxi, majusculi ; exterue pallide sed luride olivacei. Caulea 4 unc. longi, hregulariter ramosi, ramis compressis. Folia unc. longa, arete laxiusve imbricata, marginibus dorsalibus parium sub-oppositorum rotundatis postice porrectis appressis earinamque cauh quasi efficientibus ; margine superiore paido incm'vo, marginibus omnibus minute sed creberrime et regulariter dentieulatis. Perigonia in spicam brevem termi- nalem disposita.

Most nearly related to the PL fiaccida, Lindb., of St. Vincent, which has a very similarly hard and woody-stem but the present may be known by the greater breadth of its branches and foliage, by its more compound ramification and the minute denticulation of its leaves.

We have seen no Fuegian specimens of tins species. Those M. Montagne has examined, are in a very unsatisfactory state.
